Tentative Idea on Initiative Protection Technology for Lightning Stroke Based on Electric Field Cancellation Theory

Abstract:

A new technology of initiative protection for lightning stroke based on electric field cancellation theory is presented in this paper. The real time lightning detection system and the active protection equipment are adopted. By using this new method, the protection technology of direct lightning stroke can be changed from little current triggering to weakening the electric field near the weapon system, and the down leader of charged thundercloud can be repulsed by the artificial opposed field. So the lightning discharge condition in this protection region can be destructed, and the lightning hazard to the protected equipment is eliminated radically. It effectively reduces the electromagnetic radiation, ground potential reaction and step voltage caused by the high current along conducting wire in the conventional lightning rod protection technology.
